Actually the many small meals a day thing is a common myth that has been disproven many times. For the most part it doesn’t really matter how many meals you eat as long as you’re getting enough food to support muscle growth.
Eating 5 to 6 small meals a day is a great strategy to help your body build more lean muscle. Try to space the meals out every 2 to 4 hours. Each meal should have a balance of carbohydrates, proteins, and healthy fats.
